What It Is

This is a 2-pack of 22-inch replacement mower blades designed for Craftsman, Husqvarna, and Poulan Pro walk-behind mowers. It replaces OEM part numbers 331740B, 421825, 437601, and 532437601, and is intended for mulching or bagging grass on residential lawns.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Your mower must have a 22-inch cutting deck. Measure the blade length from tip to tip (center hole to tip) to ensure it matches 22 inches.
• Mounting pattern: This blade uses a standard center hole (usually 7/8-inch or 1-inch diameter) and a single bolt. Check your mower’s spindle is compatible—most Craftsman, Husqvarna, and Poulan Pro models with a 22-inch deck will work, but verify your specific model number.
• OEM vs aftermarket: This is an aftermarket blade. It should fit directly, but aftermarket blades can vary slightly in thickness or hole alignment. Compare with your old blade side-by-side before installing.

Key Things to Know

• Quality: The 5.0 rating (from 4 reviews) suggests good initial performance, but limited reviews mean long-term durability is unproven. Expect standard steel construction—not hardened or coated like some OEM blades.
• Installation: Easy for DIYers. Use a socket wrench to remove the center bolt. Torque to manufacturer specs (typically 30-50 ft-lbs). Always disconnect the spark plug and tip the mower with the carburetor up to avoid oil leaks.
• Gotchas: The 2-pack is a deal if you need two blades, but check if your mower uses a single blade (most 22-inch walk-behinds do). Also, aftermarket blades may require balancing—use a blade balancer to avoid vibration.
• Sharpness: Blades come unsharpened—you’ll need to sharpen them before first use for best cut quality.

Should You Buy It

Buy this if you have a Craftsman, Husqvarna, or Poulan Pro 22-inch mower and want an affordable 2-pack to replace worn OEM blades. It’s a solid budget option for residential use, but verify fitment and sharpen before installing. Skip if you need a specific OEM part or a heavy-duty blade for tough conditions.
